An acoustic beam simulation makes use of ultrasonic beams that are used in a phased array (PA) ultrasonic, which is considered to be an advanced method of ultrasonic testing.This method is better at finding flaws in manufactured materials such as welds. The acoustic beam simulation mimics how the ultrasonic beam in a PA probe can be focused and...

Summary

Epoxy Polyamide Painting System

Description

This specification outlines a three-coat epoxy polyamide painting system for the protection of steel surfaces subject to industrial exposure, marine environments, and areas subject to chemical exposure such as acid and alkali. This system, when properly applied and cured, is capable of giving excellent protection to steel surfaces in Environmental Zones 2A (frequently wet by fresh water), 2B (frequently wet by salt water), 3A (chemical, acidic), 3B (chemical, neutral), and 3C (chemical, alkaline), but not in potable water tanks. Although the coating herein specified has exhibited good chemical protection, its resistance against specific chemicals should, in the absence of applicable case histories, be appropriately tested.
